Before You Install

Thank you for choosing to install a Max Machinery precision ﬂ ow meter. To ensure the best experience please take a moment to read through this manual prior to installation.

When you purchased this meter a ﬂ ow engineer helped determine many of the factors that will be reviewed on the following pages. You may ﬁ nd it useful to ﬁ ll out the form below and keep it in your ﬁ les for reference.

When you are ready to install there will be a few tools you will need:

Meter Installation: The meter and transmitter A signal cable (available from factory) The display or signal processing device Indicator Manual Calibration Certiﬁ cate Bypass plumbing supplies

Many Max meters are installed and operate for decades, so having the following information in your records may prove useful. We have provided this outline as a starting point.

Meter General Description

The Max P-Series of Flow Meters are positive displacement piston type units capable of great accuracy over a wide range of ﬂ ow rates and ﬂ uid viscosities. The ﬁ ve basic sizes of this series will measure ﬂ ows from 0.005 cc/min to 35 Liter/min. Various “O” ring and internal plating options are available to meet temperature and ﬂ uid compatibility requirements.

In a piston type ﬂ ow meter, four pistons and cylinders are arranged in a radial fashion around a central crankshaft. Two ﬂ uid ports on the cylinder wall, a port at the top of the cylinder, and a grooved piston enable ﬂ uid entering the ﬂ ow meter’s central cavity to be measured and pumped out by each piston in turn. The valving action for each cylinder is accomplished by the piston adjacent to it. The accuracy of a piston ﬂ ow meter is dependent on close tolerances in the cylinder wall and piston. Max Machinery regularly holds tolerances as ﬁ ne as 0.00005 inches in the production of these meters.

The movement of the pistons is converted to a circular motion at the central crankshaft, which is coupled to a magnet in the ﬂ ow meter. This motion is sensed by an external electronic transmitter, which converts ﬂ ow into a voltage, pulse train, or current for further processing.

The Max P Series of meters can be expected to perform superbly if operated within the conﬁ nes of their design envelope. For this reason, it is important to read this manual and understand the operational requirements and limits of the meter. Our Technical Service staff will be happy to answer any questions that this manual does not cover.

Transmitter General Description

Max transmitters are designed to work with the entire family of Max Flow Meters to provide extremely precise ﬂ ow measurement in a cost effective package. Different options of industrial housings or IP66 rated explosion proof enclosures, combined with a choice of one-part and two-part, high temperature designs with remote electronics cover a wide range of application environments – from the laboratory to harsh industrial processes.

This latest generation of transmitters use modern sensor technology coupled with advanced signal processing to deliver high levels of performance and reliability. Hall sensors are used to detect the position of a driven magnet inside a Max Flow Meter. Changes in position are tracked by a microprocessor, which generates an output proportional to the ﬂ ow rate. Advanced signal processing provides both ﬁ ne angular resolution (0.36 degrees rotation) and rapid response (output updated every one millisecond).

The Max transmitter will be mated to a mechanical ﬂ ow meter, conﬁ gured, and calibrated at the factory as a set. This ensures accuracy and allows quick setup in the ﬁ eld. For ﬁ eld installations where the transmitter has not been set up with a meter at the factory, an optional serial interface kit may be purchased to give full access to conﬁ guration options and parameters.

Transmitter Features

High resolution measurement – Analog Output: Programmed output ranges to any value within ± 10 Vdc or ± 20 mA. Frequency Output: Programmed output resolution of 1 to 1000 pulses per revolution. Linearization of up to 16 points to fully describe the ﬂ ow meter’s output curve and achieve the highest system linearity over the meter’s entire operating range.

Compensation Algorithm – Compensates for variations in Hall sensor and ﬂ ow meter characteristics to provide a stable, undamped output that accurately represents the instantaneous ﬂ ow rate. This feature is factory set when the meter and transmitter are mated together. If the transmitter is changed, the compensation can be performed via a button on the circuit board.

Anti-Dither Buffer - Masks the false output that may occur at very low ﬂ ow rates in the presence of vibration or hydraulic noise. If the meter reverses direction the output signal will be interrupted for a user selected portion of a meter rotation. Reverse ﬂ ow exceeding the buffer setting will result in an output proportional to reverse ﬂ ow rate. The buffer quantity can be set from 1% to 100% of a revolution.
